Led initiatives to develop a scalable logistics platform and AI-powered features optimizing real-time order management, routing, and delivery. Designed and implemented distributed microservices in Java, Go, and Node.js with gRPC, deployed on AWS ECS with Terraform and CloudFormation. Built a high-throughput API Gateway using NGINX with secure REST APIs (OAuth2/JWT, AWS IAM) and Redis caching to enhance authentication, scalability, and reliability for high-concurrency operations. Implemented an event-driven system with Kafka and the Outbox pattern to automate compensating actions across services, improving order consistency and recovery time. Developed a real-time notification service using AWS Lambda and EventBridge, and engineered a real-time matching and routing system using Python, Redis, and ML-driven scoring with WebSocket telemetry. Migrated high-throughput fulfillment databases from PostgreSQL to CockroachDB for multi-region scaling with zero downtime. Built an LLM-powered recom

Scaled a global marketplace by migrating from a monolithic platform to microservices, building data-driven systems to support millions of users and transactions. Designed event-driven microservices with Kafka for bookings, payments, and notifications, optimizing API response times. Optimized PostgreSQL schemas and indexing, and integrated Elasticsearch and Redis caching to enhance global search performance. Built availability calendar APIs with Redis caching and distributed locks to reduce double-bookings by 40%. Implemented GraphQL queries and REST endpoints, and developed modular frontend within a microfrontend architecture using Angular and React. Improved frontend performance through code-splitting and lazy loading, and created automated tests (Cypress, Jest, React Testing Library). Built AWS infrastructure (S3, RDS, CloudFront) and CI/CD pipelines (Jenkins, CircleCI, Docker, Kubernetes) enabling blue/green and canary deployments. Mentored junior engineers and participated in code
